The chorus of the song 'Gravity' by alternative rock band 'Poets of The Fall' pretty much sums up what the new 3D space-drama flick 'Gravity' is all about. Starring Sandra Bullock and George Clooney, the movie that premiered in the 70th Venice International Film Festival in August, is hitting theatres worldwide, Friday.

Directed by Alfonso Cuarón, who co-wrote the script with his son, Jonas, the 90-minute movie is artfully packaged to keep you at the edge of your seat.

The plot of the story 'orbits' around Dr. Ryan Stone (Sandra Bullock), a biomedical engineer on her pilot trip and Matt Kowalski (George Clooney) a cowboy astronaut on the verge of retirement, going out on a space expedition 375 miles above earth. During a spacewalk, debris from a nearby satellite destroys their shuttle, leaving them stranded with limited air. More debris follows like a space catastrophe and in course, Dr. Stone separates from the shuttle's cargo bay arm and tumbles out of control.

What do you do when you have no control over your movement? You are spinning around uncontrollably in nothingness, no one or nothing to hold on to. Will you live? Will you die? Will you ever see your loved ones?

Gravity is a tale of intense struggle artfully weaved with hope. According to the Chicago Tribune, while Bullock's character is 'burdened with loss and emotional underpinning', Clooney's character is optimistic and ever-so-sunny, just like his smile!

Emotions are entwined with special effects beautifully. The silence is enthralling, irritating and terrifying. Bullock's soliloquy could get to your nerves but the true anxiety and fear of isolation comes through effectively. Some aspects of the movie, according to experts, seem logically impossible, but the whole experience is hair-raising.

So, if you are looking for some adrenaline this weekend, 'Gravity' is your movie. Also, you might just end up shedding a tear or two through your 3D glasses.

Bonus Fact: Apparently, Robert Downey Jr. was the first choice for Matt Kowalski's character but was replaced with George Clooney. Sandra Bullock was also chosen after approaching multiple other actresses.

"At once the most realistic and beautifully choreographed film ever set in space, 'Gravity' is a thrillingly realized survival story spiked with interludes of breath-catching tension and startling surprise," Todd McCarthy wrote for The Hollywood Reporter.

"Watch this film on the biggest screen you can find, in 3D IMAX if possible - not to be overwhelmed by its noise and effects, but to join its smart, soulful heroine on her incredible journey and to experience the size of its quietness," Moira Macdonald wrote for Seattle Times.
